well the oil has been changed twice sence the motor was installed and i used castro, but the car was gona be used for my daily driver, but i just didnt drive it much, because i have other cars, but it runs vine the motor i just bought from hmotorsonline and its only been in the car for a few months.and i live in morgan county that up in north alabama but i could mabe meet anyone half way, and those parts id rather not install them then sell the car that way the buyer has the option to install them or not but there very easy to put on i think its just held on by about 5 nuts and thats it
